I was doing some welding this week with the acetaline and oxygen bottels and i found out its realy hard.....

I thught it would be realy easy but turns out its not

I was Welding two sheats together and thught it looked alright with the mask on, as soon as i lifted it up both plates were warped and the weld was horible and un even i looked at it like this . lol

Need alot more practice but im glad im having ago because if there isnt a MIG about, nearly all work shops got an acetaline torch so its handy to know.


any one else hear tryed it or any good? and im gusing the weld isnt as strong as a MIG weld would be....................

and im gusing the weld isnt as strong as a MIG weld would be....................

done properly it should be as strong - a bad mig weld will not be that strong either - keep practicing - I cannot do it either!!

Well its good to know im not the only one who finds it hard. Gets realy hot as well workin in front off that torch all time, makes me feel ill if i do it for more than 4 hours or so

Oxy acetaline can produce fantastic results... but it's not a thing you can pick up after even a few months.

As you've found, it distorts flat panels very quickly, so is not suitable for a lot of thin stuff nowadays. However, with lots of practice it's still fantastic for general repairs and fabrication.
You can watch the metal heat up and run (try doing that with Mig..) and the metal doesn't even need to be clean to form a good, strong weld. There is also normally much less grinding down to do afterwards.

The chap I work with is a gas-welding pro. It is truely amazing to watch him work and see the results. However, we've decided a combination of gas, mig and spot-welding is the best way to restore a classic to concours condition

I really enjoy oxy acetyline welding. Feels like "proper" welding if you know what i mean. Love the smell it produces too. Wish i had a gas setup and some little projects to go at that i could use it on. Sure i would need a bit of practice to get the knack back again, but its all good.

A guy i used to work with swears by his acetylene welder. He's just bought a new MIG welder but said he's not throwing his bottles away because he prefers to use them, it's just the MIG is quicker lol.

Not done any Oxy acetaline welding yet, just loads of cutting!

More to do on friday, have to cut out an immersion spanner

[mini_mentalist_chris]

I have done my whole mini with oxygen and acetylene. I think it's great. It is tricky at first but you do get used to it. It's very important not to put too much heat into the panels or they do warp! Make sure the flame "cone" isn't too big / fierce. Do a few tacks first then fill in the gaps, this stops you blasting the panel with a load of heat and getting warping. If you think it's getting a bit hot, just take the torch away for a minute and let things cool down, or move to another part of the weld like at the other side or something.

and what did we weld minis up with before mig welders were invented?
oxy/acety welding can weld thinner metal than mig welders, its not just lets oxcy weld this panel up and distort it, thats why we use damp rags.
